Same Order

To process large lists of file names on machines with small amounts of
memory. Use in conjunction with `--compare' (`--diff',
`-d'), `--list' (`-t') or `--extract'
(`--get', `-x').

The `--same-order' (`--preserve-order', `-s') option tells tar that the list of file
names to be listed or extracted is sorted in the same order as the
files in the archive. This allows a large list of names to be used,
even on a small machine that would not otherwise be able to hold all
the names in memory at the same time. Such a sorted list can easily be
created by running `tar -t' on the archive and editing its output.
